COMBINATION BURNER.

Application filed June 11,

To all whom it may concern: Be it known that I, PORTER Auos MOR- GAN, a citizen of the United States, residing at Okinulgee, in the county of Okinulgee and State of Oklahoma, have invented a new and useful Combination Burner, of which the following isa specification.

This invention relates to fuel burners, the primary object of the invention being to provide a -burner which will automatically control the volume of fuel entering the burner tube proportionately to the quantity of air or steam pressure.

A further object of the invention is to provide a burner of this character which may be employed for burning powdered coal, gas, air or oil, suitable means being provided for admitting either` of the fuels to the burner tube.

With the foregoing and Aother objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodimentiof the invention herein disclosed, may be made within the scope of what is claimed, without de arting from the spirit of the invention.

eferring to the drawings Figure 1 is a longitudinal sectional view through kthe burner constructed in accordance with the present invention.

Figure 2 is a sectional view taken on line 2-2 of Figure' 1.

Referring to the drawings in detail, the reference character 5 designates the body portion of the burner which has a threaded opening to accommodate the threaded extremity of the burner tube 6 as clearly shown by Figure 1 of the drawings.

The body lportion 5 is also provided with an openin to accommodate the threaded extremity ofa pipe adapted to feed powdered coal to the interior of the burner tube, Athere being provided a suitable valve member 8 for controlling the passage of powdered coal to the burner tube. YIt will also be understood that when powdered. coal is fed to the burner tube, a suitable worm or spiral feeding member is operated in the coal feeding pipe to feed the powdered coal and prevent .clogging of the same, within the coal feeding pipe.

At the base ofthe body portion 5 is a gas 1921. Serial No. 476,791.

or air feeding piper 9, the passage of gas or air through the pipe, being controlled by the suction caused by the passage of the fuel through the fuelsupply tubes, to be hereinafter more fully described. 10 is also threaded in the body portion, and as shown, this plug is provided with a' threaded bore extendingl through the central portion thereof and adapted to accommodate the threaded pipe l2 is also threaded in the plug 1G and provides means for connecting the coupling 13 to the p lug l0, the coupling 13 being iii communication with a high pressure air or steam pipe 14, the passageof air 'or steam 70 the pipe being controlled by means through of the valve' member l5.

Extending into one 13 is a pipe 16 which which has a threaded portion operating over the threads of the pipe 16.

' Extending through the pipe 11 and disposed in. spaced relation therewith, is a tube 19 that has an angularly disposed Se flange 20 adapted to 'contact with the end of the pipe 11 to close the end thereof toV prevent the passageof air or steam theren from. This tube 19 has a threaded eztremity positioned in the coupling 21, which 25 coupling connects the oil feed pipe 22 to the tube 19, the passage of the oil through the pipe 2 2 bleing controlled by means of the valve member 23.

A coiled spring indicated at 26 encircles' passageway is provided` a. portion of the tube 19 and has vone end 10i;

thereof contacting with the cap 18, the opposite end abutting the washer 27 which is threaded on the tube 19, the threaded arrangement allowing the tension of the springQG. to be regulated at the will of the operator. Supported on one end of the controlling rod 24, is a coiled spring 28 which has one end seated on the cap 'that closes one end of the pipe 30, thepoiled spring 28 having its opposite end engag- Ho A. ping S extremity ofthe pipe 11.
